I was at one of my local parts stores with one of my parts counter friends who during process of our bench racing cession mentioned something about installing hydralic assist on my brakes he says some big trucks and campers use them.

I guess my question is has anyone ever done this is there such a thing he also mentioned useing a vacum pump from a power stroke deseil as a evac system.

Some old 5.7 and 6.2 GM diesels used a system called hydraboost for power brakes. It works very well.

Linclion was 1 of the first w/ hydraboost. uses power steering preassure to work.

Check out Hydratechbraking.com I installed one of their systems on a 1967 Camaro and it works great.

Several GM motorhomes, and some other GM car models used an electrical vacuum pump. Do a google search and you should be able to find some reference articles on the net. One article I ran across had a list of GM models with OEM pumps, so that you could try to find one in a junkyard.

FWIW, Hydroboost brakes were not JUST installed on diesel-powered vehicles.

Be aware that GM swapped from 45° Flare fittings to Metric O-Ring in about 1980.

I assume that your Chrysler is also Saginaw pump equipped, but ... you will have to either "tee" into your existing return line, or buy a different reservoir with dual return line connections ... like this one:

NAPA # 20-8609
(One return port is for the PS and the other is for the HB.)

I am installing hydroboost brakes on my 66 GMC 454, and got almost everything I needed as remanufactured products from NAPA.

See my journal (entries 31, 32) for part numbers, pictures, and further explanation.
